We used Jessica as our TA.
She is pleasant and efficient. That being said, we had two issues...
One of our ADR's (Coral Reef) wasn't booked (even though I had a reservation #), so this could have been a Disney flub.
Two, our plane reservations coming home were changed and I let Jessica know, however she never let the folks at ME know, so we had an issue with transportation back to the airport.
All in all, it was a pretty uneventful trip.
